I viewed both logs and did not saw any issues.
A desync means you have different or modified files that don't match with others players.
Validate your game files with steam. (again)2a. Delete everything inside C:\ProgramData\FAForever\gamedata\
2b. Host a game with the FAF client to redownload the files into \FAForever\gamedata\ Delete all mods, also *.SCD mods that can be located in any \gamedata\ folder (kyros lobby as example)
4a. Delete the game.prefs file located in C:\Users\YOURNAME\AppData\Local\Gas Powered Games\Supreme Commander Forged Alliance\Game.prefs
4b. Start a game via Steam and create a new player inside the game (needed after deleting game.prefs)
Then try again.
